The most unique plus point of this app is that you can set a battery limit target upto which you want to drain your battery level ( let’s say upto 20 or 30%) after reaching to that limit this app will automatically turn the drain mode off.

Impressive right?


  • Set the Drain Limit.
  • Shows useful Information like Battery Voltage, Temp etc.


  • Doesn’t support one click mode option


All of these battery drainer apps works similarly with minor differences but we recommend you to try out only if you’re aware of what are you actually doing with your devices.

Note: These apps may cause damage to you battery health and reduce its life. So, I strictly suggest you to use them wisely.
